To all whom it may concern:

Be it known that I. HARRY B. STEWART,

citizen of the United States of America, re-

siding at Lynn Creek, British Columbia, Dominion of Canada, have invented certain new and useful Improvements in Photographic-Printing Presses, of which the fol{ lowing is a specification.

This invention relates to photographic printing machines, and the primary object of the invention is to provide a novel device for mechanically printing pictures in an expedient and convenient manner, which can be utilized for commercial photography,-art photography, or the general business of amateur film developing and printing establishments, or the combination of all, so as to eliminate the time, labor and inconveniences associated with printing with the ordinary hand printing frame. v

Other objects of the invention are to provide', in a printing press or machine of the above character, a novel means for receiving a plurality of sensitized cards, paper or other printing material; a novel means for feeding the sensitized material one piece at a time to a printing frame; a novel means for urging the sensitized material into" frictional engagement with the paper feeding means; a novel means for feeding or carrying the sensitized material after the printing operation to a suitable receptacle, a novel removable and light proof receptacle for receiving the paper after the printing operation for development; a novel means for feeding the film or negative to and across the printing frame; and an improved printing means for automatically marking each piece of the sensitized material.

A further object of the invention is to provide a positive means for insuring the taking of one piece of sensitized printing material at a time and a novel means for adjusting said first named means according to the size, thickness, and general characteristics of the sensitized material being used, so as to insure the proper functioning of said first means.

A further object of the invention is to provide, in an improved sensitized printing material feedingdevice, a novel suction or.

vacuum means for attracting the sensitized material, and for holding and delivering the same to the printing frame, and a novel means for automatically, controlling the negative feeding tive strip taut in front of suction of said means according to tion of the said feeding device.

A further ob'ect of the invention is to provide means or regulating the throw of the film feeding device, so as to permit the film feeding device to be used in connection with various sizes of films.

A still further object of the invention is to provide an improved photographic printing machine or press of the above character, which is durable and efficient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

Referring to the drawings in detail,wl1erein similar reference characters designate corresponding parts throughout the several views, the letter A indicates a lower horizontally disposed card, paper or other sensitized material holding compartmennwhich forms the base for the machine; B, a means for urging the cards, paper or other sensitized material toward one end of the compartment; C, a vertically disposed head piece or frame carried by the forward end of the compartment; D, a print frame car'- ried by the head piece; E, a sliding extractor reciprocably mounted on the head piece; F, the operating means for the slide extractor; G, a suction device carried by the slide extractor and the control valve arranged thereon; H, a shearing knife or means for insuring the positive delivery of only one piece of the senstized material at a time to the slide extractor"and suction device; I, the film or negative receiving and feeding device; J a means for operating the negative or film feeding device and the adjustable stops for limiting the'movement thereof; K, a horizontally disposed compartment arranged above the lower compartment A; L, a removable light proof receptacle for receiving the cards, paper or other sensitized material after-the printing operation; and vM, the

automatic printing device for marking each one of the cards, strips, pieces of paper, or

other sensitized material.

The lower horizontally disposed compartment A for receiving the sensitized material, designated by the numeral 5 includes the side walls 6, a rear end wall 7, and a hinged top wall or cover 8. The cover 8 only covers the rear portion of the compartment and only permits the repairsor the like to the means B for urging the cards or other sensitized material 5 toward the forward end of the compartment. The other part of the upper portion :of the compartment is left open, and is normally closed by the removable receptacle L, which receives the sensi tized printingmaterial after the printing operation. The forward end of the lower compartment it. is also left open so as to permit the pack of cards or other sensitized material 5 to be urged into engagement with the slide extractor plate E. The side walls 6 and the rear end wall 7 supports a bottom wall 9, which may be of any preferred material, such as metal or the like. Owing to the fact that the sensitized material will be of various sizes to conform with the various sizes offilms or negative, the height and width of the compartment is made variable so as to conform to the size of the sensitized material being used. To permit of the size of the compartment being varied, the same includes a lower false bottom 10, and side false walls 11 which aread-apted to be moved toward and away from each other. The false bottom 10 includes a relatively long narrow body portion and outwardly extending arms 12, which are adapted to fit in cut-out portions 13 formed in the false side walls 11. These arms 12 form guides for the false side walls 11 and permit the same to be adjusted toward and away from each other. In order 1 the sensitized printing material. the bottom wall 9 is provided with a pair of spaced slots 14:. through which are adapted to ride cams 15. The cams 15 are keyed or otherwise secured to a longitudinally extending shaft 16, which is operated by means of a cross shaft 17. The cross shaft 17 can be operated in any preferred manner such as by handle 18. The cross shaft 17 is operatively connected to the longitudinally extending shaft 16 in any preferred manner such as by means of a worm and worm wheel as shown in Fi re 3 of the drawings. It can be seen that y rotating the cross shaft, the cams will be raised or lowered through the slots 14 and thus ermit the raising and lowering of the false ottom. The false side walls 11 extend the entire length of the compartment A and are adapted to be adjusted toward and away from each other synchronously. This adjusting me'ans consists of a pair of transversely extending rods 19, which have their opposite ends oppositely screw threaded and fitted in suitable threaded bores formed in the falseside plates or walls. One of the rods 19 is adapted to be operated in any preferred manner, such as by a hand crank 20, and these screws are operatively connected together by any preferred means, such as a sprocket chain and sprocket wheels, as in-' dicated by the numeral 21, the sprocket wheels being keyed or otherwise secured to the outer terminals of the rods 19. It thus c'an be seen that by turning the crank 20, the side plates or false side walls 11 may be adjusted toward and away from each other to conform to the width of the sensitized material pack 5.

It is desirable that the false bottom 10 be urged into frictional contact with the slide plate extractor E, and in order to insure of the frictional contact, a. leaf spring 22 has been shown for engaging the rear end of the false bottom '11 for normally urging the same forwardly. The spring 22 is secured in any preferred manner to a cross supporting plate 23, which is utilized for supporting spring and is slidably carried the means B, for norm'ally urging the sensitized material pack toward the forward end of the compartment. In order to adjust the tension of the spring 22, a longitudinally extending rod 24 isprovided. The forward end of this rod 24 engages the by the cross plate 23. This rod has its rear end threaded, and mounted in a guide sleeve 25. A suitable adjustin nut 26 is threaded on the threaded portion of the rod soils to move the same into and out of engagement witlr the spring 22. It can be seen that by mov ing the rod in or out, the tension of the spring 22 can be readily adjusted.

The means B for normally urging the sensitized material pack 5 toward the forward end of the compartment, consists of a follower head 27, which may be detachably carried by the forward end of a follower rod 28. 28 is provided with a piston or stop 29, which is slidably mountedwithin a longitudinally extending cylinder 30, which is arranged centrally within the compartment A. The cylinder 30 is supported by means of the cross plate 23, and the rear end wall 7, and is provided with a removable end cap 31. A n expansion coil spring 32, is mounted within the cylinder, and bears against the cap 31 and the iston 29. Thus it can beseen that the fo lower head 27 will be normally urged into engagement with the sensitized material pack 5. lVhile spring means have been shown for urging the head 27 in engagement with the sensitized material pack, it is to be understood that other means, may be employed such as compressed air or steam, which may be admitted in one The rear end of the follower rod end of the cylinder for operatin against the piston 29. If so desired, suitab e curved follower lates 33 may be interposed at any point witliin the sensitized material pack 5, so as to straighten out the natural curva ture in the sensitized material. The sensi tized material generally has a natural curvature therein caused by the application of the sensitized material thereto, and it isdcsirable that the curvature of the follower plate 33 be in a direction opposite to the curvature of the sensitized material.

The vertically disposed head piece or frame C is arranged at the forward end of the compartment A and extends above and below the same at right angles. The lower portion of the head piece or frame C which extends below the compartment A is adapted to engage the forward edge of the support upon which the machine is positioned, so as to effectively prevent movement of the machine on the support. The frame or headpiece C includes a pair of spaced side pieces. 35 which may be secured to the side walls 6 of the compartment A in any preferred manner. The side pieces35 upport a top cross piece or plate 36, and a rear wall or plate 37, which terminates short of the upper compartment A. A rectangular detachable frame 38 is arranged below the depending rear wall 37 and in engagement with the upper portion of the upper conipartment A and rests against the rear edges of the side bars or standards 35. This rectangular frame 38 is detachably held in place b suitable swinging buttons 39 orthc like. X reflector40 is carried by the frame for concentrating the light upon the printing frame D which will be hereinafter more fully described. It is to be understood that i the light for printing the pictures may be either artificial or natural. The inner surface of the side bars 35 have secured thereto at spaced points, guide rollers41, and

these rollers define therebetween a guide track for the reception of the extractor Slide plate E, which also will be hereinafter more fully described.

The head piece or frame C supports the printing frame D, and this printing frame rests upon the side walls of the upper compartment K and slidably engages the inner surface of the side bars 35. A stop 42 is carried by the frame 38 for engagin the upper surface of the printing frame so as to "prevent upward shding movement thereof. 1 The print frame D is free to slide back and forth between the side bars 35, and it is normally urged forward into engagement with the slide extractor E by means of semi-elliptical leaf springs 43. These semi-elliptical 'leaf springs 43 are carried by the rear surface of the same and engage the inner surface of the frame 28. The print frame D may be of any preferred construction and include side bars 44, and end bars 45. The side bars 44 and the lower end bar 45 may be rabbeted as at 46 for the reception of the printing glass 47. This glass 47 may he slipped down from the top of the frame.

The slide extractor E includes a vertically disposedtransversely extending plate which has a metallic backing 49, which if so desired, may be highly polished, so as to reduce the friction between the slide extractor plate and the various other working parts of the machine and track. The extractor plate E is mounted between the guide rollers 41 and is adapted to reciprocate in a vertical path between the side bars 35 for carrying one piece of the sensitized material at a time to the printing frame D, and for delivering the same to the sensitized material receiving receptacle L after the printing operation. The plate 48 adjacent to its upper end may be provided with a suitable opening 50 which may be closed by a transparent glass it so desired, and this opening forms means to permit the film to be seen without necessitating the removal of the entire extractor plate. lit is to be understood, that when the film is desired to be seen, the extractor plate E is lowered until the opening 50 comes into alignment with the print frame ll). Below the opening 50 the extractor plate is provided with a second opening 51 which may be of any desired size, and this opening has secured around the walls thereof, an annular screw threaded collar This screw threaded collar 52 is adapted to support the suction device G which will be hereinafter more fully described. The plate E may be reciprocated by any preferred means, either by hand or a motor or the like, and as shown a-means F has been provided, for reciprocating the plate.

This means F includes a pitman 5,3, the upper end. of which is secured to the lower end of the plate 48 of the means of a suitable pin "54 which is mounted in bearings 55, secured to the outer surface of the plate 48. The lower end of the pitman 53 is secured in the ordinary-manner to the eccentric pin 56, which is carried by a wheel 57. This wheel 57 is secured to a shaft 58, which can be an armature shaft of an electric motor. i

The suction .means G and the controlling valve therefor, includes a hollow head 60 which can be made of metal or any other preferred material. This head 60 is threaded on the collar 52. The extreme outer end of the head 60 is reduced and supports a valve casing 61, in which is reciprocably mounted a valve block 62. The valve block 62 is adapted to control the suction in the head 60 and has formed therein, atransversely extending port 63 which is adapted to be versely of the head extractor E by have coiled around the same suitable coil springs 69, which normally hold the valve block 62 in a neutral position so that the port 63 formed therein will be out of alignment with the bore 64 formed in the valve casing. Tn order to prevent rotary movement ofthe valve block 62 within the valve casing 61, a pin is carried by the valve casing and engages in a suitable groove 71 formed in the valve block. When the suction device Gr reaches a position where the same will be in direct alignment with the print frame D, it is desired that pressure within the head 60 be released, and to permit of the pressure in the head 60 to be equal to the atmospherical pressure, a vertically disposed bore 72 is formed in the stem 67 which communicates with a right angularly disposed port 73, which is adapted to communicate with the bore 64 formed in the valve casing. The outer end of the valve casing has connected thereto a suitable pipe 73, which may be connected with a suitable suction creating device.

A lower stop plate 74 is arranged transpiece C adjacent to its lowerend, and when the slide plate E is in its lowermost position, the stem .68 is adapted to engage the said stop plate, so as to move the valve block 62 up in the valve casing 61, so as to bring the bore or port 63 into alignment with the bore 64 of the valve casing. The head 60 will then be in directalignment with the chamber A and with the sensitized material pack 5, and this will permit of a piece of sensitized material being attracted and held by the card extractor E An upper stop plate 75 is carried by the head piece C and is arranged in parallel vertical alignment with the lower stop 74, and the same is adapted to engagethe stem 67 when the head 60 is in alignment with the print frame D. This will force the valve block 62 down in the valve casing 61, until the bore 73 comes into alignment with the bore 64, of the valve casing, which will permit of the to become equal to the atmospherlcal pressure and thus allow the sensitized piece of material to be released. The rear face of the side extractor plate E has fitted flush therewith suction plate 77, which. is provided with a plurality of conical shape openings 78. The suction plate 77 is freely removable and various kinds of suction plates are adapted to be utilized with the head 60, it being understood that they different plates will have the openings 78 formed pressure within the head 60 )late E.

therein in different formation, so that various sizes of the sensitized pieces of material can bereadily engaged. In order to hold the suction plate 77 in position, the removable bolts 79 are utilized. One end of each of the bolts 79 is provided with an enlarged head 80, which is countersunk within the suction plate. The opposite end of each of the bolts'79 is provided with a relatively small head 81, and this head is adapted to be inserted through suitable openings 82 formed in the extractor plate E. The relatively small heads 81 are adapted to be inserted in key hole slots 83 formed in locking plates 84 which are slid ably carried by the outer surface of the slide This forms a convenient means y which the suction plate can be readily removed or placed on the extractor plate E.

The means H provided for insuri the delivering of only one piece of sensitized material at a time to the extractor plate includes a transversely extending fiat bar 85, the lower end of which carries a knife 86. This knife 86 is adapted to be normally urged into engagement with the upper sur face of the sensitized material pack 5, and is so formed as to permit only one piece of the sensitized material being lifted at a. time by the extractor plate E. This means H is adapted to be adjusted in accordance with the character of the sensitized pieces of material being utilized and has the endsthereof reduced to provide arms 87, which are extended through suitable slots 88 formed in the side walls of the compartment K which will be hereinafter more specifically described and in the side bars 35 of the head piece or frame C. Around the edges of each slot 88 formed in the side bars 35 a suitable frame may be placed and a coil spring 89 is arranged within the slot, and engages the lower wall thereof and the lower surface of each arm 87 for normally urging the plate 85 upward. 'The outer ends of the arms 87 are bifurcated as at 90 for the reception of the threaded rods 91. These rods are adjustably carried by suitable brackets 92 secured to the outer surface of the side bars 35. These rods 91 have threaded thereon thumb nuts 93. which bear against the upper surface of the arms 87, and form means for adjusting the position of the plates 85 vertically inrelation to the sensitized material pack 5. In order to permit the knife H to be adjusted toward or away from the extractor plate E so as to conform to the thickness of the pieces of sensitized material being used, a pair of metal liner strips 95 and 96 are arranged in each one of the slots 88 formed in theside bars 35. The metal liner strip 95 is adapted to be adjusted by means of t nsion screws 97 which are threaded into nuts 98, carried by the outer surface of the side bars. It can be seen. that by adjusting the tension screws 97 that the liner plate 95 can be brought toward or'away from the reduced arms 87 of the plate 85, thereby permitting the plate to be adjusted accordlng to the thickness of the sensitized material being-used. In order to normally urge the liner plate 96 into engagement with the arms 87 of the plate 85 and hold the same in engagement with the liner plate 95, a pair of slidin pins 99 are carried by the bars 35, and ave mounted thereon collars 100, which are adapted to be engaged by expansion coil springs 101 which normally tend to urge the pins outwardly. The pins 99 are provided with heads which extend beyond the rear side faces of the side bars 35, and these heads are adapted to be en gaged by a vertically disposed plate 102 which is carried by the cam strap 103. The cam strap 103 is placed around a cam 104 in the usual manner, and this cam is carried by a crank 105. It can be seen that by turning the crank. the plate 102 is forced into or out of engagement with the pins 99 for urging the same toward or away from the liner plate 96. By independently adjusting the tension screws 97, it can be seen that the plate 85 can be held at various angles which is sometimes advantageous inthe using of packs of sensitized material.

.The film or negative receiving and feeding device I consists of a pair of rollers 106' and 107'. which are rotatably mounted in extensions formed on the top wall 36 and in outwardly extending bearing members 108 carried by the outer surfaces of the side bars 34. The rollers 106 and 107 extend above the top wall 36 and the roller 106 constitutes the means upon which the film strip, designated by the numeral 110, is adapted to be initially wound. The upper end of this roller 106 is provided with an operating crank 111, by means of which the film can be easily wound thereupon. The portions of both-of the rollers 106 and 107 -arranged between the bearing brackets 108 are suitably graduated as designated by the numeral 112, and a collar 113 is adjustably mounted on each of the rollers and is adapt ed to be set upon the rollers according to the size of the films or negatives from which the pictures are being printed. It can be seen that the collars 113 can be readily adjusted on the rollers and held at the desired place shown by the 'graduations 112 formed thereon. The roller 106 is provided with any suitable type of spring clip 114 for engaging the inner end of the film strip 110, and it can be seen that the film strip can be placed underneath of the clip 114, and the roller then rotated by means of the crank 111, in a direction forwinding the film strip thereupon. The bearing brackets 108 which rotatably supports the roller 107 also supports a shaft 115' on. which a. roller each of the rollers.

116 is mounted. The roller 116 is provided for frictionally engaging the film strip 110 which are'detachably secured to the lower brackets 108. a Each of the rollers 106 and 107 have a. depending stem 119 secured thereto, which extends into the caps 118.

The terminals of the sprin'gs 117 are secured respectively to the caps 118 and stems 119. These springs are adapted to be wound so as to normally tend to rotate the rollers 106 and.107 away from each other. which will hold the negative film taut. and thus prevent the crinkling thereof during the printing process. \Vhile an uncut film strip has been shown n position, it is to be understood that the improved machine and printing method is adapted to and can be effectively used to advantage in printing from individual film negatives or glass negatives. Individual film'ncgatives may be secured to the glass support proper or preferably secured to another film strip, which acts as a guide or .belt for the same. In addition the improved machine is highly adaptable to the use of glass negatives and is especially rapid and efiicient in quantity production with post cards or other prints large or small. besides being possible to print more than one negative at the same time.

The means .1 for operating the roller 107 for moving the film strip across the print frame D so as to permit the different negatives to be brought into alignment therewith. includes the outwardly extending crank 120 which is carried by the roller 107. This crank 120 is operable over a sector 'plate 121 which may he graduated as at 122. These graduations conform to the various lengths of negatives. and adjustable stops 123 are provided and mounted on a sector plate 121. The stops 123 are adjusted according to the length of the negatives so as to limit the throw of the lever 1 20. The stops are held in adjusted positions by means of suitable set screws 121 which are adapted to impinge against the outer surface of the sector plate. Vhen it is desired that a new negative be brought into alignment with the print frame D after the printing of each picture. a cable 125 may be secured to the handle 126 of the lever. and placed around suitable guide pulleys 127 and then attached to the slide extractor plate E adjacent to the lower end thereof as indicated by the numeral 128. Thus it will be seen that when the extractor plate E is moved downwardly for receiving a new piece of sensitized material, the lever J will be swung forwardly which will operate the roller 107 in such a manner as to pull a new film negative in front of the print frame D.

\Vhen it is desired, however. that a number of prints be made off of the same negative, the cable 125 is detached from the lever 120 and the same is operated by hand. Suitable hinged covers 130 are provided for housing the portions of the rollers upon which the film strip is adapted to be wound. In order to prevent retrograd movement of the roller 107 during the return movement of the crank 120. a pawl and ratchet mechanism is provided. A. pawl 120 is carried by the crank 120 and is adapted to engage the annular rack 121 formed on the roller 107. An expansion coil spring 119 is provided for normally returning the crank 120 to its normal position in engagement with the rearmost stop 123, and this spring is secured respectively to the crank121 and to a casing 118 which is connected by means of brackets 117 to the top bar 36.

The printing means M for marking each one of the pieces of sensitized material con sists of a stamping block 131', which adapted to support a plurality of changeable characters or type 132. This block is hingedly connected as at 133 to the extractor plate E and is adapted to be swung back and forth through an opening 131 formed therein. A spring 135 is utilized fornormally holding the print block 131 from out of engagement with the forward piece of sensitized material. and this spring is provided with a bowed arcuate portion 136. This bowed arcuate portion is adapted to be engaged by the bight portion 137 of' a U- shaped guide member 138. the legs of which are suitably mounted in guide eyes 139 carried by the side extractor plate E. The upper ends of the legs of the U-shaped guide member 138 are adapted to normally extend above the upper edge of the extractor plate, and when the extractor plates are moved to their uppermost position, the same are adapted to engage a cross bar 110. This cross bar 140 pushes downwardly upon the U- shaped guide member 138, which forces the bight portion 137 thereof into engagement with the arcuate bowed portion 136 of the spring 135. This will swing the block 131 nwardly with considerable force, and thus bring the type or marking characters into engagement with the forward piece of sensitized material. \Vhen extractor plate E has been moved to anuppermost position. the bight portion 137 of the U-shaped guide 138 will be moved to such a position as to permit the print block 131 to be swung outwardly, and upon downward movement of the extractor plate E, the tension of the spring 135 will be sutlicient as to again raise the U-shaped guide 138 in th guide eyes 139. A suitable inking brush 141 is provided for the type, and this brush is mounted upon a resilient leaf spring 142, which is supported by an ink cup 143 which is adapted to receive any surplus ink that may run from the brush.

If so desired, a spring operated roller 50 may be carried by the upper end of the side bars 35, and this spring operated roller may have a suitable curtain 51 wound thereupon, the lower end of which may be secured by a rod 52 to the upper end of the extractor plate E. This forms a means for automatically returning the extractor plate E to its normal raised position and prevents the riding of dirt and the like into the printing frame D.

The compartment K which is mounted upon the lower compartment A receives the removable print receiving light proof receptacle L, and this compartment K consists of the side walls 144, and the relatively thick rear wall 145. The relatively thick rear wall 145 supports the hinged cover 8 of the lower compartment A. An upper cover 146 is provided for the upper compartment K and this cover is connected by means of suitable hinges 147 to the frame 38, as clearly shown in Figure 3 of the drawings.

The print receiving light proof receptacle L is removably fitted within the compartment K and consists of the front and rear converged Walls 147, which supports the bottom wall 148. The rear wall engages a suitable spring 149 carried by the rear wall 145 of the compartment K, and this spring normally tends to lift the light proof receptacle L from out of the compartment. A top wall 150 is provided for the receptacle L and covers the'rear portion thereof and slidably supports a spring pressed cover 151 which is adapted to normally close the forward portion ofthe receptacle. The sliding cover 151 is normally urged to the forward end of the receptacle by means of an expansion coil spring 152, which is secured respectively to the rear end of the sliding cover and to one of the side walls of the receptacle. A suitable guide 153 is carried by the frame 38, and this guide is in the nature of a stop and limits the forward movement of the sliding coverin the. receptacle, when the receptacle is positioned in the compartment K. This prevents the entire closing of the lid so as to permit the riding of the sensitized material after the printing operation'into thelight proof receptacle L. It can be seen that as soon as the receptacle is removed from the compartment, and the lid 151 is brought from out of engagement with the guide and stop 153 and the spring 152 will urge the same to a closed light proof position. A resilient guide 154 is carried by'the forward end wall of the receptacle K and normally tends to guide the printed pictures into the receptacle. The extreme upper forward end of the resilient guide 154 carries a knife 155, which frictionally engages the inner surface of the extractor slide E, and forms the means for stripping the sensitized material from the extractor plate E after the printing operation.

lVhile it is preferred that the means carried by the extractor plate E be operated automatically, for. attracting and lifting the pieces of sensitized material from the pack 5, it is to be understood that the same can be manually operated if so desired.

In Figure 15 is illustrated a means for manually creating a suction, and in this form a suction rubber vacuum cup 169 is secured, by means of a ring 161, to an annular head piece 162, which is threaded into engagement with the collar 52 carried by the extractor plate E. This vacuum cup is formed of flexible material, such as rubher, as stated, and is provided with a handle 164. This handle 164 is adapted to be thrust inwardly and outwardly when the extractor slide E comes into alignment with the pack 5, so as to permit of the extracting of one of the pieces of sensitized material. After the extractor plate has moved the sensitized material to a position. in alignment with the front of the printing frame D, the handle 164 is again pushed inwardly, which will permit of the releasing of the piece of sensitized material.

The print frame D has secured thereto adjacent to its upper and lower ends pairs of rollers 45, which protrude beyond the forward surface of the print frame. These rollers normally tend to move the print frame D rearwardly against the tension of the leaf springs 43 so as to permit an opening to be made between the print frame D and the slide extractor E after the printing operation, so as to'allow the pieces of sensitized material to be dropped into the receptacle L. The inner face of the extractor plate E is provided with pairs of semi-circular recesses 43 which are adapted to receive the rollers 45 when the suction device G carried by the extractor plate E comes into alignment with the print frame. This permits the print frame D to ride for- Wardly into frictional tight engagement with the negative strip, thus preventing the entrance of light to the pieces of print paper or othersensitized material, during the printing operation.

In operation of the improved printing machine, the cover 146 of the compartment K is swung open and the receptacle L is iii removed, which permits the easy placing of a pack of the sensitized material to be used into the compartment A. The follower head 27 is forced rearwardly against the tension of the coil spring 32, until the pack has been placed in position, after which the follower head is permitted to engage the rear portion ofthe pack. This will normally urge the pack into frictional engagement with the sliding extractor plate E. The side walls 11 and the false bottom wall are, of course, to be adjusted to the height and width of the sensitized material, so as to prevent the creasing or distortion thereof during the printing operation.

' The film strip is then placed in position as heretofore described, and the device is then ready for operation. The shaft 58 of the operating means F of the slide extractor plate E is then set in motion in any preferred manner and the control valve 60' for the suction head 60 is opened so as to permit the withdrawing of the air from the head 60 when so desired. Upon the downward movement of the extractor plate E and when the head 60 comes into engagement with thepieces of sensitized material, the stem .68 will come into engagement with the plate 74 as hereinbefore described, which will permit the air to be exhausted from the head 60. A card then will be attracted. and when the suction head 60 comes into alignment with the print frame, atmospherical communication is made in L the head 60 by means of the upper stop plate 7 which will permit of the releasing of the print paper or other piece of sensitized material brought into operative posi tion in relation to the negative. 'The print is then exposed to the light, which may be either artificial or natural; as desired, for

the desired length of time, after which the extractor plate E is then brought downwardly which will move the print frame D rearwardly and permit the knife- 155 to strip the piece of printpaper or other sensitized material which has been acted upon,-

from the extractor plate E and permit the same to drop into the receptacle L. This operation is continuous and thus it can be seen that the prints can be made in an expeditious and convenient. manner without any trouble on the part of the operator.

The roller 116 is covered with antislipping material, such as rubber and is held against-retrograde movement by means of a pawl and ratchet mechanism 117' which also insures uniform and accurate feed of the film strip.

Changes in details may be made without departing from the spirit or scope of this invention; but,
